282. Using SNIC resources to explore the flow physics around a simplified tractor-trailer model

Mr Jan Östh (Chalmers University of Technology)

Poster Session

This poster will present how the use of the SNIC computational resources has been used by the authors to explore the flow physics of a simplified tractor-trailer model. Even though the geometry is rather simple, the flow around a simplified tractor-trailer model is very complex. It is characterized by large, unsteady vortices that are shed from the geometry. The interaction of these...

276. Flow simulation and optimization using SNIC resources

Mr Eysteinn Helgason (Chalmers University of Technology)

Poster Session

At present the landing gear is becoming the dominant source for noise in large airplanes. Simulations of airflow around a simplified landing gear of an airplane have been performed in order to determine pressure fluctuations around the landing gear. Different simulations methods have been compared which gives us information on how to evaluate landing gear performance without having to...

277. Massively Parallel Large Scale Automated Adaptive Finite Element CFD

Mr Niclas Jansson (KTH CSC/NA)

30/08/2010, 16:47

Poster Session

We present recent advances on automated adaptive finite element CFD for massively parallel architectures, illustrated by high Reynolds number flow simulations and adaptive computation of aeroacoustic sources for rudimentary landing gear. Our implementation shows excellent performance and scalability for a wide range of different architectures, and is freely available as part of the open...

279. HPC at KTH Mechanics

Mr Antonios Monokrousos (KTH Mechanics), Mr Peter Lenaers (KTH Mechanics), Dr Philipp Schlatter (KTH Mechanics)

Poster Session

High Performance Computing (HPC) has matured into a well established tool for cutting edge studies in fluid mechanics, both within academic research as well as at the corresponding areas of industry (aeronautics, vehicle, energy etc). Within KTH Mechanics, Computational Fluid Dynamics (CFD) also has a long tradition, dating back more than 25 years. The last few years have been...

280. Origin of the Anomalous Piezoelectric Response in Wurtzite ScxAl1-xN Alloys

Ferenc Tasnadi (IFM LiU Theoretical Physics)

30/08/2010, 16:50

Poster Session

Recently Akiyama et al. [1] have discovered a tremendous about 400% increase of the piezoelectric moduli in ScxAl1-xN alloys in reference to wurtzite AlN, around x = 0.5. This is the largest piezoelectric response among the known tetrahedrally boundend semiconductors. Since AlN can be used as a piezoelectric material at temperatures up to 1150 C and it easily can be grown as c-oriented,...

281. Multi-scale QM/MM high performance computing design of biological markers

Dr Zilvinas Rinkevicius (Department of Theoretical Chemistry, KTH)

30/08/2010, 16:51

Poster Session

Hybrid quantum mechanics/molecular mechanics (QM/MM) methods combined with molecular dynamics simulations for conformational sampling provides a unique opportunity to understand action mechanisms of optical and magnetic probes at the microscopic level. These methods are capable to predict optical and magnetic properties of biomarkers in solution and in protein environments with...

284. Chalmers e-Science Centre - a new initiative

Dr Pär Strand (Chalmers University of Technology)
